This Bonsai comes from my 16' street tree I have some 7 plants that came from seeds for the street tree. These all grew in our pots around our house

This one was OK but had very UGLY roots so last September 2018 I decided to try and "Layer" the tree off the old truck so getting a full set of new roots. The tree one year later has produced a full spread around the truck after spending 9 months in a big pot. It was a case of remove the whole lot protecting the roots as much as possible then raking them clear of the soil . Wash the soil completely away from the roots ready for trimming to fit inside the pot I had chosen for it.The tree has had the last of the old truck cut off below the root line, all the roots spread out flat (After a hair cut to fit the pot) to get use to a bonsai pot and further thicken below the ground level.

Next year I will repot and lift the plant higher to show the roots on the surface.now the real shaping begins. The wires are to just support the trunk in one position and not to move in the winds.
